Ramon Francisco Barajas Jr.

Dr. Ramon Francisco Barajas Jr., M.D., is a physician-scientist and Professor in the Department of Diagnostic Radiology at Oregon Health and Science University (OHSU). He leads multidisciplinary research on brain tumors, focusing on quantitative imaging genomics, neuroinflammation biomarkers, and molecular radiotheranostics. His work is supported by grants from the NIH NCI (K08 CA237809-01A1), OHSU Friends of Doernbecher, and the Hildegard Lamfrom Research Scholar Award.

Education & Training:

• M.D., 2009, University of San Francisco School of Medicine
• Residency: Diagnostic Radiology, University of California San Francisco (2010-2014)
• Fellowship: Neurological Radiology, UCSF (2014-2015)

Research Interests: Dr. Barajas integrates advanced imaging techniques (e.g., PET/MRI, ferumoxytol-enhanced MRI) to study tumor biology and therapeutic response in glioblastoma. His team develops biomarkers to distinguish pseudoprogression from recurrence and optimize immunotherapy strategies.

Grants & Awards:

• NIH NCI K08 Award (2015–present)
• OHSU Knight Cancer Institute Research Scholar Award
• ECOG-ACRIN Cancer Research Group Site Investigator
• T32 NIH Biomedical Imaging Training Grant (2013–2014)

Clinical Trials: Leads investigator-initiated trials, including NCT03649880 assessing FMISO PET/MRI biomarkers in glioblastoma.

Labs & Teams: Collaborates with the Advanced Imaging Research Center at OHSU and co-founded the ASNR/ASFNR/ASPNR Gene & Cell Therapy Study Group.
